Horizontal FRP Vessel

Fiberglass horizontal storage tanks are made of glass fiber reinforced plastic
and installed with their main axis parallel to the ground . They are typically
manufactured as a single unit in the factory and then transported to the site
for installation and use. The main manufacturing process involves fixed-length
winding combined with hand lay-up to produce end caps and installation
accessories.
Structural design features
Tank body :
Cylinder : Typically manufactured using a winding process, primarily
circumferential winding, to provide circumferential strength against internal
pressure. Axial strength is provided by the superposition effect of multiple
layers of cross-winding or circumferential winding.
Heads : Typically elliptical or dished heads . This streamlined design
facilitates stress distribution and provides significantly better pressure
resistance than flat heads. Heads are mostly produced by hand lay-up or
compression molding.
Support system : This is one of the most critical components of a horizontal
storage tank.
Saddle bearing : the most commonly used type of support, usually consisting of
two bearings.
Fixed end support : One of the support has round bolt holes to secure it
completely.
Sliding end support : The anchor bolt holes of the other support are elongated
holes, which allow the storage tank to expand and contract with temperature
changes, preventing excessive thermal stress.
